If you set up a camera to take a selfie whilst doing a side plank you will see abs emerging over time as the abdominal fat gets used up, or you could see them slowly dissappear as you accumulate more bodyfat.

I reckon if you use the same mirror and the same lighting all the time and a tape measure and a $5 caliper you would get a fairly good idea of what is changing.Ī cheap caliper and tape measure, used consistently, will give numbers you can monitor in your diary or a spreadsheet and will definitely tell you whether bodyfat around the measuring points is increasing or decreasing. ![]() That can be validated with DEXA or Hydrostatic Static Weighing performed by a University Lab with trained Technician.Ĭlick to expand.I went from 100+kg to 78 then deliberately back up to 90+ and now on the way down again, some observations follow that might be helpful, am keen to hear from others regarding how they do the measurements. The PN Calculator has an even greater variance of accuracy. the PN Calculator is garbage.Īll of the various method of measuring Body Fat Percentage aound educated guesses.Īll method have plus/minus variance of accuracy. Yes, they are well regarded with nutirition and suggestion on training. It bring into question other information that they might present. Ironcially, trust can quickly be damaged or destroyed with inaccurate or misleading information.īased on the PN Calculator article, there has been some damage done. The foundation of trust in an individul, organization, company, etc is built on providing accurate information.,īuilding trust is something the occurs overtime and not overnight. That can be validated with DEXA or Hydrostatic Static Weighing performed by a University Lab with trained individuals. If someone is not using this approach, the reliability of the reading is called into question. ![]() They will use a black marker to mark the exact spot. How accurate Calipers are is primarly dependent on a well trained Technician who has performed hundreds of test.Ī good Technician will use a tape measure to measure the precise spot to measure each time. ![]() His estimation is it's 15 -20% is more realistic. However, I doubt the Bill body fat percentage is 26%. Since I don't know him, it is hard to make much of an evaluation.
